Microprocessor Replacement
This document provides the procedures for replacing the Intel®Pentium®II
microprocessor(s) in a Dell PowerEdge 2200 system.
Precautionary Measures
Before you perform any of the procedures in this document, take a few
moments to read the following warning for your personal safety and to prevent
damage to the computer system from ESD.
WARNING FOR YOUR PERSONAL SAFETY AND PROTECTION
OF THE EQUIPMENT: Only trained service technicians should per-
form the following procedures. Before you start to work on the
computer, perform the following steps in the sequence listed.
1. Turn off the computer and any attached peripherals.
2. Disconnect the computer and any attached peripherals from their
power sources to reduce the potential for personal injury.
3. Disconnect any communications cables.
4. Wear a wrist grounding strap, and clip it to any unpainted metal sur-
face on the computer chassis.
If a wrist grounding strap is not available, touch any unpainted
metal surface on the back of the computer chassis to discharge any
static charge from your body.
WARNING: The power supply in this computer system produces high
voltages and energy hazards, which can cause bodily harm. Only trained
service technicians are authorized to remove the computer cover and
access any of the components inside the computer.

Replacing a Microprocessor
In addition to the connector for the primary microprocessor on the system
board, there is a second connector to accommodate a secondary microprocessor.
(In a single-microprocessor system, a terminator card is installed in the second
microprocessor connector.)
The secondary microprocessor must have the same operating frequency as the
primary microprocessor. For example, if the system has a 300-MHz Pentium II
primary microprocessor, your secondary microprocessor must also be a
300-MHz Pentium II microprocessor.
Use the following procedure to install a microprocessor:
1. Enter the System Setup program and check the system BIOS revision.
The BIOS revision must be A05 or higher.
If the system has a BIOS revision lower than A05, follow these steps to
update the BIOS:
a. Insert the BIOS diskette that came in the replacement kit into drive A.
b. Turn on the system.
c. After the system completes the boot routine, follow the instructions on
the screen.
d. After the BIOS has been successfully installed message
appears on the screen, remove the diskette from drive A and follow the
instructions on the screen to reboot the system.
2. Save the EISA Configuration Utility settings to the EISA Configuration
Utility Diskette provided in the replacement kit.
The EISA Configuration Utility must be version D07 or higher to recognize
the 300- and 333-MHz microprocessors. An updated version of the EISA
Configuration Utility Diskette has been included in the replacement kit; use
it instead of the EISA Configuration Utility on the Dell Server Assistant
CD. Follow these steps to save the settings:
a. Insert the EISA Configuration Utility Diskette into drive A and reboot
the system.
b. When the Welcome screen appears press <Enter>. The Main Menu
appears.
c. Select Step 5: Save and Exit, and then follow the online instructions to
save the current system configuration information.

3. Remove the computer cover (see Figure 1).
a. Remove the four screws along the back edge of the cover. If a keylock
screw is installed in one of the cover-mounting screw locations, use the
key provided with the system to remove it.
b. Slide the cover backward about an inch; then grasp the front of the cover
and the handle at the back of the cover, and lift the cover straight up off
the chassis.

4. If you are adding a secondary microprocessor, remove the terminator
card from the second microprocessor connector (see Figure 2).
NOTE: If you are not adding a secondary microprocessor, do not remove the
terminator card. Go to step 5.

Figure 2. Removing a Terminator Card
a. Remove the terminator-card retention bracket cover that holds the termi-
nator card in place. Using the thumb and forefinger of each hand, pinch
the vertical tabs at each end of the cover, and then lift the cover straight
up.
b. Remove the terminator card. Holding the card by its edges, lift the card
straight up from the microprocessor retention bracket.
5. If you are upgrading an existing microprocessor, remove the micro-
processor module as follows.
a. Using a 1/4-inch nut driver, remove the two hexagonal screws securing
the microprocessor module to the system board assembly (see Figure 3).
WARNING: The microprocessor-module heat sink can get extremely
hot. Be sure that it has had sufficient time to cool before proceeding.

b. Carefully lay the system on its right side so the microprocessor mod-
ule(s) are visible from the top.
c. Disconnect the temperature sensor cable from the system board and the
microprocessor module.
d. Press inward on the microprocessor-module retention latches until they
snap into a retracted position (see Figure 4).

tion Bracket

processor retention bracket on the system board.

6. Install the new microprocessor module.
a. Make sure the new microprocessor-module retention latches are in a
protracted position so that the retention latches will snap into position
when the microprocessor module is installed.
b. Align the microprocessor module with the microprocessor retention
bracket on the system board.
c. Lower the microprocessor module into the microprocessor retention
bracket, and press firmly on the top of the module until the module is
fully seated and the retention latches snap into position (see Figure 5).

7. Reinstall the two screws securing the microprocessor-module heat sink
to the system board assembly.
Stand the system upright, and reinstall the two hexagonal screws in the
system board assembly.
8. Change the microprocessor speed jumper setting to correspond to the
new microprocessor’s operating frequency.
The microprocessor speed jumper should be set for the installed micro-
processor’s rated internal speed. For a 300-MHz Pentium II processor, a
jumper plug should be installed on the jumper labeled “RSVD1.” For a
333-MHz Pentium II processor, a jumper plug should be installed on the
jumper labeled “RSVD2” (see “System Board Jumpers” found later in this
document).
NOTE: The system BIOS revision must be A05 or higher to use the RSVD1
and RSVD2 jumpers.

9. Connect the temperature sensor cable to the microprocessor module
and to the system board.
The cable for the primary microprocessor attaches to the TEMP_1 connec-
tor on the system board, while the cable for the secondary microprocessor
attaches to the TEMP_2 connector on the system board. The connectors on
the cable are keyed to ensure proper orientation.
10. Replace the computer cover.
11. Reconnect your computer and peripherals to their power sources, and
turn them on.
As the system boots, it detects the presence of the new microprocessor and
automatically changes the system configuration information in the System
Setup program.
12. Enter the System Setup program, and confirm that the Processor 1 and
Processor 2 categories correctly identify the installed microprocessor(s).
13. Run the system diagnostics to verify that the new microprocessor is
operating correctly.
See Chapter 2, “Using the Dell Server Assistant CD,” in the Dell Power-
Edge 2200 Systems User’s Guide for information on running the diagnostics
from the Dell Server Assistant CD. The Diagnostics and Troubleshooting
Guide provides additional information on running the Dell Diagnostics and
troubleshooting any problems that may occur.
